As the owner of an old clunker, I was used to dealing with a variety of car breakdowns. One day at the supermarket, just after I had filled my trunk with groceries, I noticed a stream of fluid pouring out of the bottom of the car. I knew I had to get home before the car was once again out of action.

When I arrived I asked my husband to take a look at the problem.

Expecting the worst, I braced myself for his diagnosis. When he came back in, he was smiling. "It's apple juice," he said.
